It’s pretty hard to deny that split-flap displays are incredibly awesome. This one has been a long time coming, and it’s not a refab or surplus build. [Tom] fabricated these beautiful alpha-numeric split flaps from scratch.
Having recently seen an alarm-clock split flap hack just a week or so ago we found ourselves wondering where in the world people manage to find this type of awesome mechanical hardware. If you can’t get it out of grampa’s attic, the next best thing is to build it from the ground up.
This was not a build to be taken lightly. [Tom] started years ago, and part way into the project we looked at some of the control hardware for the installation. Make sure that you dig deep into his blog posts. It’s the only way you’ll put together the whole picture of how he ended up with each belt and stepper motor driven character module.
